The Elite Builder became one of the most popular jigs when it comes to fabricating a 5.56 or 9mm 80% lower. Now, The Elite Builder Patriot Jig can complete virtually all the AR platforms' 80% lowers! We included new template plates so the jig can also cut and drill .308 lowers. Now it's a top choice for completing an 80% 6.5mm or AR-10 / LR-308, too. Pair it with the Patriot Pack and get all 3 lowers with your jig. With its hardened alloys and precision drill bushings, the Elite Builder will knock out your forged, billet, and polymer receivers with tolerances as close as 0.001".
HSS Bits for Multiple Builds
The jig’s only as good as the bits you use it with. So, the Elite Builder includes quality industrial-grade HSS (high-speed steel) drill bits and end mill bits to cut through all that aluminum in no time. All you need to complete your receiver blank is a basic drill press and about two hours’ time. The tool kit includes:
- (1) ⅜ Drill Bit - 5”
- (1) 5/32 Drill Bit - 3”
- (1) ⅜ Short End Mill - 3”
- (1) 5/16 Short End Mill - 4”
- (1) ⅜ Long End Mill - 4”
